ADAM11 of 769 aas and 2 TMSs, N- and C-terminal.  Probable ligand for integrin in the brain. This is a non catalytic metalloprotease-like protein.  ADAM11 is essential for proper localization of Kv1.1 and Kv1.2 K+ channel subunit complexes to the distal tubule plasma membrane.  It is the first Kv1 interacting protein to be discovered (Kole et al. 2015). It has four domains recognized by CDD: Pep-M12B - Proopep - ZnMc/Reprolysin - Disintegrin.

Disintegrin, a metaloprotease (sheddase) of 824 aas and 2 TMSs near the protein's N- and C-termini.  Sheds many membrane-bound proteins, especially receptors, with a preference for acidic amino acids at the P1' position. Cleaves membrane proteins and modifies their activities while releasing the proteotytic products into the external medium (Pupovac and Sluyter 2016).  ANO6 (TC# 1.A.17.1.4), by virtue of its scramblase activity, may play a role as a regulator of the ADAM-network in the plasma membrane.

Metalloproteinase of 775 aas and 2 TMSs, N- and C-terminal, Adam28. Epididymal metalloproteinase-like, disintegrin-like, and cysteine-rich protein II. May function in ectodomain shedding of lymphocyte surface target proteins such as FASL and CD40L. May also be involved in sperm maturation (Jowett et al. 2012).

Adam10 of 748 aas and 2 TMSs, an N- and a C-terminal TMS (Prox et al. 2012).  Both ADAM10 and ADAM17 shed CD16b (Guo et al. 2012) and CD23 (Mathews et al. 2010).  By destroying cell-cell contacts through cleavage of cadherins, the metalloproteinase ADAM10 (a disintegrin and metalloproteinase 10) critically contributes to α-toxin-dependent pathology of experimental S. aureus infections in mice. ADAM10 is a receptor for α-toxin (von Hoven et al. 2016; Virreira Winter et al. 2016). ADAM10 is docked to junctions by its transmembrane partner Tspan33, whose cytoplasmic C-terminus binds to the WW domain of PLEKHA7 in the presence of PDZD11. ADAM10 is locked at junctions through binding of its cytoplasmic C-terminus to afadin. Junctionally clustered ADAM10 supports the efficient formation of stable toxin pores. Instead, disruption of the PLEKHA7-PDZD11 complex inhibits ADAM10 and toxin junctional clustering. This promotes toxin pore removal from the cell surface through an actin- and macropinocytosis-dependent process, resulting in cell recovery from initial injury and survival (Shah et al. 2018).

ADAM12 of 909 aas and 2 TMSs, N- and C-terminal.  Involved in procession amyloid-beta (TC#1.C.50) (Malinin et al. 2005). Also involved in skeletal muscle regeneration, specifically at the onset of cell fusion, and in macrophage-derived giant cells (MGC) and osteoclast formation from mononuclear precursors.  It is a four-leafed clover: the excised prodomain remains bound to the mature enzyme (Wewer et al. 2006).

Ats1 or ADAMTS1 of 967 aas. A disintegrin and metalloprotease with thrombospondin motifs 1. Cleaves aggrecan, a cartilage proteoglycan, and may be involved in its turnover. Has angiogenic inhibitory activity that may be associated with various inflammatory processes as well as development of cancer cachexia (Vázquez et al. 1999).

A disintegrin and metalloproteinase with thrombospondin motifs 4, ADAMTS4, of 837 aas and 2 TMSs, one N-terminal, and one near the C-terminus. Cleaves aggrecan, a cartilage proteoglycan. May play a role in the destruction of aggrecan in arthritic diseases. Could also be a critical factor in the exacerbation of neurodegeneration in Alzheimer disease. Its synthesis is regulated by Aqp1 (TC# 1.A.8.8.1).

Metalopeptidase (sheddase), Meprin A, MEP1B of 701 aas and 2 TMSs, N- and C-terminal.  It has three domains, N-terminal: ZnMc metal protease; Middle: MAM extracellular receptor domain, and C-terminal: MATH domain (see CDD). Proteolyzed and sheds many membrane-bound proteins. Shows a preference for acidic amino acids at the P1' position. Cleaves membrane proteins and modifies their activities while releasing the proteotytic products into the external medium (Pupovac and Sluyter 2016).
